2D-arrrays of Cu Nanodisks on Anodic Aluminum Oxide (AAO) Template for SERS Applications
Main Article Content
Abstract
Abstract. Copper nanodisks (Cu NDs) of 50 nm in size were prepared on square-inch anodic aluminum oxide substrates by RF-sputtering method. The samples were annealed at 450oC, then the walls of anodic aluminum oxide (AAO) substrates were lift off in a solution of acid phosphoric. The 2D arrays of Cu NDs were fabricated in high quality. Morphology of the substrates was observed by scanning electron microscopy. Surface plasmon resonance absorption was observed with different peaks in the range of 400-1400nm wavelengths that means the substrate is promising for SERS application. The Raman spectrum of Rhodamine 6G loaded on AAO substrates was much enhanced.
